R3117Nxx3 Series Low Voltage Detector with SENSE Pin for Automotive Applications
2022-02-14
● OUTLINE:
■ The R3117Nxx3 is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely low voltage and is used for system reset as an example. The IC consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver and a hysteresis circuit. The detector threshold is fixed with high accuracy internally and does not require any adjustment.
■ The tolerance of the detector threshold is ±15mV (-V-DET < = 1.5V) or ±1.0% (1.5V< -V-DET ). Since the sense pin is separated from the V-DD pin of the IC, therefore, even if the sense pin voltage becomes to 0V, the output voltage keeps its "L" level.
■ Two output types, Nch open drain type and CMOS type are available. The R3117Nxx3 supports the SOT-23-5 package.
